Definitions

  • the purpose of the Invention Patent herein is to register a counter-die cylinder for a stamping machine that incorporates significant innovations and advantages.
  • the invention relates to a counter-die cylinder applicable in particular to a rotary stamping machine for stamping laminar material that comprises a cylindrical body that rotates on its own axis, at least one tubular element arranged around the cylindrical body and one shroud arranged around the corresponding said tubular element, allowing axial movement of the tubular element.
  • a type of rotary stamping machine for example that used in the manufacture of boxes from corrugated cardboard sheets based on passing a sheet of corrugated cardboard between two cylinders, is provided with a die-holder cylinder where the die and a counter-die cylinder are mounted and provided with shrouds that are usually made of plastic laminar material, such as polyurethane, where the blades for cutting the corrugated cardboard are sunken.
  • the shrouds usually become unevenly worn over time by repeated penetration of the die-blades, resulting in areas with a significantly smaller diameter and, therefore, areas of lesser penetration or lesser pressure of the blades, a fact that may cause problems during stamping operations so much that it can prevent cutting and/or cause problems related to splitting.
  • a first known solution to prevent this uneven wearing involves rectifying the surface of the blades regularly.
  • this solution requires downtime in production and/or in turn causes accelerated wear of said shrouds.
  • a counter-die cylinder for a machine for stamping laminar material of the type that comprises a cylindrical body that rotates on its own axis, at least one tubular element delimiting two opposite ends (for example, on the lateral edge itself or by means of buffer rings located at each end) that is arranged around the cylindrical body and at least one shroud arranged around said tubular element and is characterized in that it comprises movement means linked to the buffer rings for moving in a longitudinal direction with respect to the axis of the cylindrical body of the aforementioned tubular element, such that the position of the tubular element can vary along the length of the cylindrical body, said movement means being actuated by automated actuation means.
  • the shrouds can move axially automatically without having the disadvantages mentioned above, i.e. the service life of the shrouds is extended without the need for honing the shrouds since wearing occurs uniformly and in turn movement of the structure described to move said shrouds is automated.
  • the movement means and automated actuation means are located inside the cylindrical body. In doing so, no additional space is required to arrange the movement mechanism for the shrouds by making use of the space inside the cylindrical body which is usually hollow and empty inside, and consequently there is no interference with other equipment or components in the machine.
  • the movement means comprise at least one pushing element associated with the automated actuation means.
  • the counter-die cylinder comprises a counter-pressure element that exerts a force opposite to the force exerted by the pushing element.
  • the pushing element comprises a pusher member located on an axially movable axis that passes through the inside the cylindrical body provided with an engine that can be a geared motor, the pusher member being in direct contact with a buffer ring arranged at one end of the tubular element.
  • the counter-pressure element comprises a pneumatic cylinder housed securely inside the cylindrical body that includes a pusher member that is in direct contact with a second buffer ring arranged at the end opposite to the previously mentioned end.
  • the pusher member that is part of the pusher element and the counter-pressure element comprises an annular body provided with at least one retention tab that protrudes outwards and movable along a raglet located in the cylindrical body, the annular body being integrally secured to a spindle connected to the motor and to the pneumatic cylinder, respectively.
  • the movement means and automated actuation means may be located on the outside of the cylindrical body.
  • the cylindrical body of the counter-die cylinder is provided with at least one access door to access the inside a simple and practical manner, such that in the case of maintenance or repair or replacement of any of the components that may be located on the inside, complete disassembly of the counter-die cylinder is not required.
  • the counter-die cylinder comprises synchronization means, such that the linear speed of the movement means is synchronized with the rotational speed of the rotating cylindrical body.
  • Such means are associated with a control unit in the machine which is arranged in the counter-die cylinder.
  • an embodiment of a counter-die cylinder for a stamping machine for laminar material (not shown), indicated generally by reference 1, particularly suitable for stamping corrugated cardboard boxes, comprises an elongated cylindrical body (2) that rotates on its own axis and is horizontally coupled to the frame or bed of the stamping machine by means of two circular metal (9,10) plates at each end, which are each provided with axis-centred support and rotation (16, 17) respectively through which the rotational movement of the counter-die cylinder (1) is transmitted in a known way so it is not necessary to go into greater detail.
  • a plurality of aligned tubular elements (3), arranged on the outer surface of the cylindrical body (2) and a plurality of shrouds (4) are provided, for example, polyurethane, each of which is arranged around its corresponding tubular element (3).
  • the counter-die cylinder (1) is provided with movement means, which will be detailed hereinbelow, that allow movement, in a longitudinal direction, of the tubular elements (3) along with shrouds (4) with respect to the axis of the cylindrical body (2), such that the position of the tubular element (3) can vary along the length of the cylindrical body (2) by a relatively slow swinging movement of the shroud, i.e., from one end of the machine bed to the other on which the counter-die cylinder (1) is arranged, with said movement means actuated by automated actuation means which can be actuated by means of a button located on a part of the stamping machine or connected to the actual functioning of the counter-die cylinder (1).
  • such movement means comprise a pusher element (5) associated with automated actuation means and a counter-pressure element (6) capable of being moved that exerts a force opposite to the force exerted by the pusher element (5).
  • this comprises a pusher member located on an axially movable axis (7) that passes through the inner cavity of the cylindrical body (2) that is provided with a reduced size geared motor (8), with dual rotation direction while the pusher member is in direct contact with a buffer ring (12) arranged at one end of the tubular element (3).
  • the counter-pressure element (6) comprises a pneumatic cylinder (11), connected to a supply of compressed air that may be associated with other parts of the stamping machine, whose pneumatic cylinder (11) is housed inside the cylindrical body (2) and is integrally secured on the inside thereof.
  • Said counter-pressure element (6) includes a pusher member movable by means of the cylinder (11) piston (19), which is in contact with a second buffer ring (13) arranged at the end opposite to the previously mentioned end. While the counter-die cylinder (1) is operating, this pneumatic cylinder (11) exerts a constant pressure on the buffer ring (13) that can be adjusted if so required.
  • the axis (7) always works against the force exerted by the pneumatic cylinder (11) and is responsible for transmitting the final movement of the shrouds.
  • the changing rotating direction of the axis (7) can be carried out using detector elements or limit switches located on both the outside and inside of the counter-die cylinder (1).
  • the two aforementioned pusher members each comprise an annular body (14), 14' respectively, provided with retention tabs (15, 15') that protrude radially outwards and movable along raglets (18) located in the cylindrical body (2) in a radial arrangement, with the number of raglets (18) equal to the number of retention tabs provided.
  • retention tabs (15, 15') consist of metal plates that have a protuberance on the upper part that acts as a buffer with a flange on the buffer ring.
  • Figure 4 shows a sequence of three stages where the movement of the shrouds (4) to the left of the image can be seen, such that the buffer rings (12 and 13) move together with the shrouds (4) by means of the retention tabs (15, 15'). Additionally, this figure shows the arrangement of the die-holder cylinder above the counter-die cylinder (1) described in the memory herein.
  • the movement means and motorized actuation means may be located outside the cylindrical body, which have used the same reference numerals for the common elements with the previously described embodiment.
  • the movement means of the counter-die cylinder comprise a pair of pins (20), (21) each associated to respective buffer rings (12), (13) located at the two opposite ends of the counter-die cylinder (1), performing the swinging movement of such pins (20), (21) in a similar manner to the pusher members described previously along a spindle (22) which runs in parallel and separately to the counter-die cylinder, as indicated by arrows in Figure 5 .
  • each of the pins is provided with a geared actuation system (23), (24) respectively which is integral to the corresponding pin (20), (21).
  • buffer rings (12), (13) may have an additional incorporated mechanism that rotates with the tubular elements on which the shrouds are, preventing wear as a result of friction during movement.
  • cylindrical body/bodies and shroud(s) can form a single integral body axially moveable without thereby departing from the scope of protection defined by the characteristics in claim 1.
